Research Of The Structure Of Network Inquiry Learning Platform Based On X3D

By the end of 20 century, the information technology application had opened the mordern distance learning prologue, with the information technology powerful support,the modern distance learning has already developed from the edge pattern of education to the mainstream pattern..Many kinds of learning platform with different functions have been emerged as the times require.These learning platform mainly use multimedia to exhibit the teaching content.Tht application of these learning platform are restricted with the information capability and network bandwidth, and these learning platform are devoid of alternation.Virtual reality noted for its high quality in three-dimension modeling,freedom interaction and low-requirement for hardware and software configure is favored by web-based education,which qualifies itself as an important media technology for implement web-based explore learning. The education pattern and methodology will be reformed and popularly deployed correspondingly. As a new learning method with the use of VR related products, in one part, learners can get experiments and tastes from the reality world; in the other part, educators such as teacher's cangradually teach students by means of pedagogical thinking of the new digital era. Because X3D technology has ultra and new characteristic and strong function, undoubtedly it has great potentiality in the field of virtual reality. As X3D becomes the new standard of the network 3D, and is constantly improved, constructing the modern long-range education system based on X3D has already becomethe important subject.In this thesis, the author strive to implement learning platform based on X3D and ASP.NET.The thesie expatiated the relationship with education and virtual reality and discussed the mutual infection with virtual reality and learning theroy.The purpose is to establish the academic basic of the learning platform based on X3D.The theses also expatiated the advantages of using virtual reality technology to develop virtual Laboratory and the influence of the applying Virtual Reality in education field;researched into the modeling technology of virtual experiment based on virtual reality and introduced development course, characteristic, makes-up and key technology of X3D briefly.Because the core of the learning platform is virtual experiment,the thesis research into modeling technology of virtual experiment based on virtual reality and researched into cartoon technique,andio technique and interaction technique X3D, and analyzed the way of applying these techniques in designing virtual experiment. Put forward the elementary model of the learning platform based on X3D, analyzed the function of each module in the model of the learning platform based on X3D, brought forward detailed methods of realizing each function module in the learning platform based on X3D.
